Abstract

A method and apparatus for transmitting/receiving multi-channel audio signals is provided. The apparatus for transmitting multi-channel audio signals includes: a multi-channel audio down-mixer configured to receive a multi-channel audio signal and transform the multi-channel audio signal into a down-mixed audio signal and a supplementary signal; a super frame generator configured to generate a super frame including a plurality of supplementary signal frames; and a packetizer configured to packetize the super frame, wherein the super frame includes supplementary signal frame number information and supplementary signal frame length information of the supplementary signal frames included in the super frame.

Description

technical field [0001] The present invention relates to a method and device for sending and receiving multi-channel audio signals, in particular to a method and device for using super frames to send and receive multi-channel audio signals. Background technique [0002] Recently, there are many researches on methods of multi-channel audio coding. Also in the Moving Picture Experts Group (MPEG) surround technology, the encoding / decoding method of multi-channel audio is standardized, and a method of encoding down-mixed multi-channel audio into a stereo audio signal and an additional signal is used. At this time, the down-mixed stereo audio signal is encoded according to an audio coding method such as Advanced Audio Coding (AAC), Bit Sliced ​​Arithmetic Coding (BSAC), etc., suitable for its application. [0003] At the same time, Digital Multimedia Broadcasting (DMB), as a multimedia service that can be received in a mobile environment, forms services through terminals such as ...
